Answer & Explanation:
Crest is a point in the cycle where maximum or peak amplitude exists. In another way, it is a point on the positive side of a wave where maximum amplitude exits. Trough is a point in the cycle where minimum amplitude exists.
Crest: points A and E
Trough: points C and J
Wavelength is the distance between two crests or two troughs. One example is distance between points A and E.
Frequency is 3 because there are 3 oscillations in 1 second (follow the line from beginning to point D, then D to G, the G to end).

Answer : The final concentration of the seawater is, 2.909 mole/L
Explanation :
Formula used for osmotic pressure :
where,
= osmotic pressure = 70.0 bar = 70 atm
R = solution constant = 0.0821 Latm/moleK
T= temperature of solution = 
C = final concentration of seawater = ?
Now put all the given values in the above formula, we get the concentration of seawater.
Therefore, the final concentration of the seawater is, 2.909 mole/L
